May sound silly but what does morning sickness feel like? Pregnancy symptoms?? Pls help!!

For the past few days my boobs and nipples are sore and tender that I can’t touch them. And I’ve also felt sick when my boobs started to hurt. I feel nauseous and feel like I’m going to throw up but never do and my tummy is cramping. I’m not sure if I’m pregnant because I’m waiting for my scan next week. However when I’ve spoken to friends who have been pregnant they say that’s my symptoms are similar to pregnancy. Do you have to throw up for it to be morning sickness? Ive missed a few pills around the time I think I could’ve gotten pregnant and yesterday I had unprotected sex and he came in me and I’ve had to double pills cos I missed a few. Can someone help me pls??
